Use a non-_ name for arguments

The new version of `pydoclint` doesn't allow to document arguments named
`_` (it complains with "Docstring contains more arguments than in
function signature.").

Instead of removing the documentation, we can just rename the arguments
to have a more sensible name, which should make the test more readable
anyway.
